Embodiment Construction

[0031] The principle is introduced, such as using a sphere, cutting a sphere (the size can be arbitrary, even a complete sphere), as the range of the head rotation.

[0032] Such as figure 1 As shown, the center of the sphere is O, which is the position of the person; the center of the cut sphere is point P, that is, the initial orientation is that the person stands at point 0 and looks towards point P; the edge is ACBD; if it is a complete sphere, then With any point as the center, the intersection point of the reverse extension line and the sphere is the boundary, and the edge will degenerate into a point at this time. The areas where the head can rotate are AOB and COD. For the convenience of subsequent description, we establish a three-dimensional coordinate system, with the OP as the Z axis, the horizontal as the X axis, and the vertical as the Y axis.

[0033] Euler angle introduction: In computer 3D graphics, Euler angle is a very commonly used rotation, which is repr...

Abstract

The invention provides a VR display method and a system for 3D video. The VR display method for 3D videos comprises: A) obtaining the Euler angles by an inertial measurement unit; B) obtaining the polar coordinate of the cutting sphere from the Euler angles, the sphere being a carrier for playing the 3D video; C) obtaining the viewing angle for watching the 3D video from the polar coordinate; and D) playing video according to viewing angle. According to the invention, the 3D video could be on VR display, which overcomes the technical problems in prior art, meets the requirement of users and can be promoted widely for applications.

Description

technical field [0001] The invention relates to the technical field of video processing, in particular to a VR display method and system for 3D video. Background technique [0002] Virtual Reality (Virtual Reality_VR) is a hot spot now, and currently only panoramic videos can be viewed in VR. However, the production of panoramic video content is more difficult, so there is not much content. [0003] The current method of playing VR video is: draw the video in a sphere, cube or other geometry, and then calculate which part of the sphere the human eye needs to watch according to the data from the inertial measurement unit (English: Inertial measurement unit_IMU), where the IMU is used to Measure the three-dimensional rotation of the human head. [0004] After years of development, 3D video has a wide range of content. However, because 3D video is not a panoramic video, it cannot be directly drawn on a sphere, otherwise the deformation will be very serious. How to make 3D vid...
